Obama briefed, calls Patrick and Menino

President Obama spoke to Massachusetts Gov. Deval Patrick and Boston Mayor Thomas Menino on Friday afternoon as he continued to be briefed on developments there, a White House official said.

Obama was briefed just before 4 p.m. in the Oval Office by Assistant to the President for Homeland Security and Counterterrorism Lisa Monaco, the official said, and he then called Patrick and Menino.

The president expressed his condolences for MIT officer killed overnight and "said that the entire country is behind the people of Boston as well as Massachusetts, and that the full force of the Federal Government will continue to be made available until those responsible are brought to justice," the official said.

The White House has been quiet all day Friday, offering a few updates on Obama's latest briefings, but declining to comment on the status of the manhunt and investigation underway in Massachusetts.

This post has been updated after the White House corrected its original statement, which said the president expressed his condolences for the deaths of "two officers."
